ย 

In Chile, a big telescope is being built in the Atacama desert. It’s called the Extremely Large Telescope, or ELT. This telescope will be the biggest in the world. Dr. Elise Vernet is helping to make sure the mirrors work perfectly.

In Germany, a company called Zeiss is making special mirrors. These mirrors help make tiny computer chips. They can reflect light very well, which helps make the chips better. Zeiss wants to help make super powerful chips by 2030.

Mirrors are very important for new technology. They help us see faraway stars and make better computer chips. These mirrors are made with very careful designs. They help us learn more about space and improve technology on Earth.

Group or Classroom Activities

Warm-up Activities:

– Charades
Instructions: Write down key words related to the article on small pieces of paper (e.g., telescope, mirrors, technology, space). Have students pick a piece of paper and act out the word without speaking while the rest of the class guesses what it is.

– News Summary
Instructions: Divide students into pairs. Have one student summarize the main points of the article to their partner in their own words. Then, have the partner do the same. Encourage them to use the vocabulary from the article.

– Vocabulary Pictionary
Instructions: Write down key vocabulary words from the article on the board (e.g., telescope, mirrors, technology). Have students take turns coming to the board to draw a visual representation of the word while the rest of the class guesses what it is.

– Opinion Poll
Instructions: Create a list of statements related to the article (e.g., “Do you think exploring space is important for humanity?” “Should countries invest more in technology research?”). Have students move around the classroom and ask their classmates for their opinions on each statement, practicing expressing their own opinions as well.

– Two Truths and a Lie
Instructions: Have each student come up with two true statements and one false statement related to the article. In small groups, students take turns sharing their statements, and the rest of the group has to guess which statement is the lie. This helps students practice expressing information from the article in a fun way.
